09 Ago AC 110V/220V to DC 12V 15A 180W Universal Regulated Switching 15A, Black
Left is: AC 110V, Right is AC 220V. There is a yellow botton on the right corner. Dust the switcher out every 2 or 3 months if necessary. Then wait about 10 minutes. It will be auto recovered. Then reconnected it, it will work well....
